Documentation/printk-formats.txt says to use %zd for a ssize_t argument and some drivers do. Unfortunately this prints a positive number for negative values eg: tpm_tis 70030000.tpm_tis: tpm_transmit: tpm_send: error 4294967234 Add a case to va_args a ssize_t type if the interpretation should be signed. Tested on PPC32. Signed-off-by:

The boot_delay parameter affects all printk(), even if the log level prevents visible output from the call. It results in delays greater than the user intended without purpose. This patch changes the behaviour of boot_delay to only delay output. Signed-off-by:

Currently getting the sample period is always thru a complex calculation: get_softlockup_thresh() * ((u64)NSEC_PER_SEC / 5). We can store the sample period as a variable, and set it as __read_mostly type. Signed-off-by:

The {read,write}s{b,w,l} operations are not defined by all architectures and are being removed from the asm-generic/io.h interface.

Will Deacon authored
The {in,out}s{b,w,l} functions are designed to operate on a stream of bytes and therefore should not perform any byte-swapping, regardless of the CPU byte order. This patch fixes the generic IO header so that {in,out}s{b,w,l} call the __raw_{read,write} functions directly rather than going via the endian-correcting accessors.

Since userspace headers were moved to generated/uapi it possible to have a stale copy of linux/version.h at that file's old location. This causes confusion after building an older kernel version, then checking out and building a new one; the old (stale) version header will still get picked up until it is manually removed. This upsets the C library. Since the uapi changes, include/linux/version.h is no longer generated and should not be ignored, so this patch removes it from .gitignore. Signed-off-by:

Currently the __define_initcall() macro takes three arguments, fn, id and level. The level argument is exactly the same as the id argument but wrapped in quotes. To overcome this need to specify three arguments to the __define_initcall macro, where one argument is the stringification of another, we can just use the stringification macro instead.

Current mem= implementation seems buggy because the specification and implementation don't match. The current mem= has been working for many years and it's not buggy - it works as expected. So we should update the specification. Signed-off-by:

This reverts commit 8fa72d23. People disagree about how this should be done, so let's revert this for now so that nobody starts using the new tuning interface. Tejun is thinking about a more generic interface for thread pool affinity. Requested-by:

Pull block layer core updates from Jens Axboe: "Here are the core block IO bits for 3.8. The branch contains: - The final version of the surprise device removal fixups from Bart. - Don't hide EFI partitions under advanced partition types. It's fairly wide spread these days. This is especially dangerous for systems that have both msdos and efi partition tables, where you want to keep them in sync. - Cleanup of using -1 instead of the proper NUMA_NO_NODE - Export control of bdi flusher thread CPU mask and default to using the home node (if known) from Jeff. - Export unplug tracepoint for MD. - Core improvements from Shaohua. Reinstate the recursive merge, as the original bug has been fixed. Add plugging for discard and also fix a problem handling non pow-of-2 discard limits. There's a trivial merge in block/blk-exec.c due to a fix that went into 3.7-rc at a later point than -rc4 where this is based." * 'for-3.8/core' of git://git.kernel.dk/linux-block: block: export block_unplug tracepoint block: add plug for blkdev_issue_discard block: discard granularity might not be power of 2 deadline: Allow 0ms deadline latency, increase the read speed partitions: enable EFI/GPT support by default bsg: Remove unused function bsg_goose_queue() block: Make blk_cleanup_queue() wait until request_fn finished block: Avoid scheduling delayed work on a dead queue block: Avoid that request_fn is invoked on a dead queue block: Let blk_drain_queue() caller obtain the queue lock block: Rename queue dead flag bdi: add a user-tunable cpu_list for the bdi flusher threads block: use NUMA_NO_NODE instead of -1 block: recursive merge requests block CFQ: avoid moving request to different queue -

Andrea's autonuma-benchmark numa01 hits kernel BUG at huge_memory.c:1474! in change_huge_pmd called from change_protection from change_prot_numa from task_numa_work. That BUG, introduced in the huge zero page commit cad7f613 ("thp: change_huge_pmd(): make sure we don't try to make a page writable") was trying to verify that newprot never adds write permission to an anonymous huge page; but Automatic NUMA Balancing's 4b10e7d5 ("mm: mempolicy: Implement change_prot_numa() in terms of change_protection()") adds a new prot_numa path into change_huge_pmd(), which makes no use of the newprot provided, and may retain the write bit in the pmd. Just move the BUG_ON(pmd_write(entry)) up into the !prot_numa block. Signed-off-by:
